Abstract
The invention discloses a rubber softening agent and a preparation method thereof. The rubber softening agent comprises the following raw material in part by weight: 10 to 30 percent of asphalt and 70 to 90 percent of naphthenic oil. The preparation method comprises: heating the asphalt to 80 to 100 DEG C till the asphalt is molten; fully stirring the molten asphalt, and keeping the temperature between 80 and 100 DEG C constantly for 50 to 70 minutes; adding naphthenic oil according to a corresponding ratio, heating the mixture at a constant temperature to 100 to 120 DEG C for 40 to 60 minutes with full stirring; and cooling, storing at room temperature for 24 to 27 hours and producing the rubber softening agent. The nontoxic asphalt-modified rubber softening agent which used to lack in China does not reach safety standards of European Union, thereby saving cost of China's tire manufacturers considerably.
Description
Technical field
The present invention relates to a kind of Rubber Softener and preparation method thereof, specifically, is a kind of Rubber Softener for tire and preparation method thereof.
Background technology
The used domestic Rubber Softener of tyre production enterprise does not meet European Union's safety standards at present, and the tire that directly causes producing can not export to European Union member countries.
Summary of the invention
Technical problem to be solved by this invention is, a kind of Rubber Softener for rubber tyre and preparation method thereof is provided.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of Rubber Softener, formed by following materials based on weight:
Pitch 10%-30%
Naphthenic oil 90%-70%.
The preparation method of described Rubber Softener may further comprise the steps successively:
(1) pitch is heated to 80 ° of C-100 ° C, is liquid and melts shape, fully stir, constant temperature keeps 80 ° of C-100 ° C, and the time is 50--70 minute;
(2) naphthenic oil of adding corresponding proportion, thermostatically heating fully stirs to 100-120 ° of C, and be 40-60 minute heat-up time;
(3) after the cooling, under the room temperature situation, deposited 24-27 hour, make the Rubber Softener of asphalt modification.
The invention has the beneficial effects as follows: the Rubber Softener of asphalt modification of the present invention, product is nontoxic, is lower than European Union's safety standards, has filled up the blank of domestic production, has saved the cost of domestic tyre production enterprise greatly.
